BICYCLE.

SPECIFICATION forming part of Letters Patent No. 582,595, dated May 1 1,189'?.

Application filed September 24, 1896. Serial No. 606,841. (No model.)

T0 all whom t may concern:

Be it known that I, JOHN A. ANDERSON, a citizen of the United States,residingin Takefield, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Bicycles, ofwhich the following is a specification.

This invention relates to mechanism intermediate of the pedals anddriving shaft whereby the driving-wheel may be operated to a greateradvantage and with greater or less power or speed at the will of therider and its speed quickly checked in case of necessity through themedium of the pedal.

The nature of the invention is fully described in detail below andillustrated in the accompanying drawings, in which- Figure l is a sideelevation of a sufficient portion of a bicycle to illustrate myinvention. Fig. 2 is a vertical section taken through the drivingmechanism on line X, Fig. 3. Fig. 3 is a section taken on line Y, Fig.2. Fig. 4t is a section in detail taken on line Z, Fig. l. Fig. 5 is anenlarged detail showing the rear end of the brake-rod and itsconnection, looking from the inner or rear side.

Similar letters of reference indicate corresponding parts.

a and b represent, respectively, portions of the frame and thedriving-wheel.

d is the driving-shaft, and A is the hub thereon, extending up into theflange A' (from which the spokes extend) and formed into the drum A".

B is a sleeve loose on the hub A and form ed with the integral disk oriiange B', which extends up to the drum A" and constitutes with saiddrum and said flange A' a case for the dogs C, which are pivoted at O'to the portion B' and are held by the springs O" against the inner sideof the drum A".

A suitable cord or chain D has one end secured at D' to the annularledge B", formed on the part B', while the opposite end is secured at Dto the segment E, whose shank E' is adj ustably secured at e to theupright F', pivotally secured at f to the bracket H', extending downfrom the collar H, which is rigidly secured to the portion ct' of theframe. Integral with this upright F' is a forwardextending arm F, whichis adj ustably secured at g to the lever J, which supports the pedal K.This construction of course is duplicated on the opposite side of thewheel. Pressing down the pedal K swings down the lever J, and with it ofcourse the arm F, thus causing the segment E to swing forward, so thatthe cord D imparts partial rotation to the case B', causing the dogs Oto clutch the drum A" and impart similar rotation to the hub A and henceto the wheel Z9. Vhen the pedal is relieved from pressure, the case B'is returned to its original position in the ordinary manner by means ofthe spring L, which c011- nects said case with the frame, the dogs Cslipping back within the drum in the manner common in such mechanisms.To increase the power, the lever J is drawn rearward and readjusted withrelation to the arm F, or the shank E', which is the short arm of thelever, is lowered on the upright F', or both said adjustments may bemade. To increase the speed, the lever J is pushed forward, or the shankE' is raised, or both may be done. As will readily be seen, the parts Fand J constitute the long arm and the parts F' and E the short arm of anelbow-lever, both such arms being adjustable as to length.

A brake-band consisting, preferably, of the metallic outside strip P andleather inside strip P', is secured at one end at S to the frame, thenceextends around the drum A", and is secured at its other end to thebrakerod R, which extends to the upright F', which is rigid to theframe. The rear end of the brake-rod R is provided with a slot T, Fig.5, whereby it is engaged by the pin T', extending from said upright F'.The ordinary downward stroke of the pedal does not cause this pin toreach the rear end of the slot T; but should the rider desire, as incase of danger, to apply the brake to the machine he can do so instantlyby lengthening the downward stroke of the pedal, so that the lost motionis taken up and the pin T' strikes the rear end of the slot T and drawsforward the brakerod R, thus applying the brake-band P to the drum A".Thus the brake may be applied instantly without using the hands.

Having thus fully described my invention,

IOC

what I claim, and desire to secure by Letters Patent, is-

1. In a bicycle of the character described, in combination, the frame;drivingshaft; hub provided with the flange A and drum A"; the clutchingmechanism adapted to engage said drum; the brake-band P secured at oneend to the frame and extending partially around the drinn; the swingingsegment E provided with the shank E; the pedallever F F pivotallysecured to the frame and supporting said segment and shank; theconnecting-rod R secured at one end to the brakeband and slotted at T atthe other end; and a pin or bolt T extending from the portion F of saidlever into said slot, substantially as set forth.

2. In a bicycle of the character described, in combination, a druminclosing the mechanism for imparting motion to the Wheel; a band-brakedisposed around said drum; a lever actuated by the pedal and pivotallysecured to the frame of the machine; a driving connection intermediateof and connecting said lever and drum; and a brake-rod secured at oneend to the band-brake and by means of the slotted connection at theother end to the pedal-lever, whereby a len gthened stroke of said leverwill apply the brake, substantially as described.
